Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.It should be appreciated that following signal
Property embodiment and explanation only be used for explain the present invention, it is not as a limitation of the invention, and, in the case where not conflicting,
The feature in embodiment and embodiment in the present invention can be combined with each other.
As shown in Fig. 1 ~ Fig. 6, the embodiment of the present invention provides one kind without operating rope curtain rope control device, including pedestal 1
With the pressing plate 2 that pedestal 1 is articulated in by means of rotating shaft 42；The pressing plate 2 is provided with pedestal 1 with the use of the pressure to step up or release
Conjunction portion（The non-label of figure）, the pedestal 1 is provided with the first friction mandrel 11 towards the side of nip portion, and the nip portion is towards pedestal 1
Side be provided with the second friction mandrel 21 shifted to install with first friction mandrel 11；The one end of the pressing plate 2 is additionally provided with fix bar
41, one end of the drawstring 3 of curtain connects the withdrawing rope device 5 of curtain, and the other end of drawstring 3 is from first friction mandrel 11 and the
Passed through between two friction mandrels 21, and the curtain 6 of curtain is connected to after the fix bar 41 is bypassed, when curtain 6 is moved up and down, pressure
Conjunction portion 41 rotates relative to pedestal 1 between clamped position and disengaged position around the shaft under the drive of drawstring 3, and nip portion is located at folder
During tight position, second friction mandrel 21 promotes the drawstring 3 to be wriggled between the first friction mandrel 11 and the second friction mandrel 21 to wear
OK.
The embodiment of the present invention sets the first friction mandrel 11 on pedestal 1 and the second friction mandrel 21 is set on pressing plate 2, passes through
Using cooperatively for first friction mandrel 11 and the second friction mandrel 21, can effectively increase the frictional force between the present apparatus and drawstring 3, and
By changing the quantity and position relationship of the first friction mandrel 11 and the second friction mandrel 21, the first friction mandrel 11, the can be controlled
The size of the frictional force between two friction mandrels 21 and drawstring 3；First friction mandrel 11 is superimposed by curtain gravity in itself, second is rubbed
The frictional force between axle 21 and drawstring 3 is wiped, can mutually be maintained an equal level with the pulling force of withdrawing rope device 5 so that the curtain 6 of curtain can be adjusted arbitrarily
Whole height, facilitates the descending operation of curtain 6.
In one alternate embodiment, the pressing plate 2 includes two blocks of parallel side plates 22, two end-rack of the fix bar 41
Between one end located at the biside plate 22 away from nip portion.
In the present embodiment, setting fix bar 41 can have the strong point rotated with dynamic pressure plate 2 as drawstring 3, using thick stick
Rod principle, can cause that pressing plate 2 is moved toward the direction away from pedestal 1 when curtain 6 is shunk in withdrawing rope device 5.
In one alternate embodiment, the pedestal 1 is provided with the groove for accommodating the nip portion（The non-label of figure）, institute
The first friction mandrel 11 is stated to be set up between the both sides cell wall of groove.
In the present embodiment, groove is set and is conducive to fixing the position of nip portion so that pedestal 1 and pressing plate 2 are between the two
With the use of more firm；Can cause that device is more simplified simultaneously.
In one alternate embodiment, when the nip portion is located at clamped position with the pedestal 1, first friction mandrel
The distance between 11 upper lateral margin and groove bottom wall of the groove are more than the lower lip of the second friction mandrel 21 and the groove of the groove
The distance between bottom wall.
In the present embodiment, the distance between the upper lateral margin of the first friction mandrel 11 and groove bottom wall of the groove are rubbed more than second
The distance between lower lip and groove bottom wall of the groove of axle 21 are wiped, can guarantee that drawstring 3 rubs with the first friction mandrel 11 and second
Wipe axle 21 and there is contact area between the two, possess frictional force.
As shown in fig. 7, in one alternate embodiment, the friction mandrel 21 of first friction mandrel 11 and second is by shaft core 211
Constituted with the friction material layer 212 being wrapped in outside shaft core 211.
In the present embodiment, increasing friction material layer 212 can have so that drawstring 3 fits in the first friction mandrel 11 and second completely
The surface of friction mandrel 21, effective the increase friction mandrel 11 of drawstring 3 and first and the second friction mandrel 21 contact area between the two, from
And improve frictional force.
In one alternate embodiment, first friction mandrel 11 is no less than three with the total quantity of second friction mandrel 21
The difference of the quantity of root and the quantity of the first friction mandrel 11 and the second friction mandrel 21 is not more than 1.
In one alternate embodiment, second friction mandrel 21 is set up between the biside plate 22, and the side plate
22 root edge is further opened with corresponding with the first friction mandrel 11 keeping away a recess 24.
In the present embodiment, set it is corresponding with the first friction mandrel 11 keep away a recess 24, can play fixed limiting first and rub
Wipe the effect of axle 11, can also cause the second friction mandrel 21 with the first friction mandrel 11 shifting to install by a larger margin.
As shown in Fig. 8 ~ Fig. 9, in one alternate embodiment, the rotating shaft 42 is located at pressing plate 2 away from the one of fixing axle 41
End；In another alternative embodiment, the rotating shaft 42 is located between the fixing axle 41 of pressing plate 2 and nip portion.
In the present embodiment, the rotating shaft 42 can flexibly be arranged at one end or middle part of pressing plate 2, effectively according to lever principle
Raising device flexibility.
In one alternate embodiment, the pedestal 1 and pressing plate 2 use injection moulding integrated molding.Using integrated through injection molding into
The mode of type is conducive to improve production efficiency, saves production cost.
As shown in Figure 10 ~ Figure 11, specifically used mode of the invention is：The one end of drawstring 3 is connected to the curtain 6 of curtain, separately
One end is connected to withdrawing rope device 5.It is now, described without operating rope window by curtain 6 toward drop-down when needing that curtain 6 is outer drop-down
Curtain drawstring control device is in clamped position, and second friction mandrel 21 promotes the drawstring 3 in the first friction mandrel 11 and second
Wriggled between friction mandrel 21 and walked, so that frictional force is produced between the friction mandrel 11 of drawstring 3 and first and the second friction mandrel 21,
So that curtain 6 is fixed on optional position；When needing the up time receiving of curtain 6, due to curtain 6 gravity under human factor with
The strength of operator holds perseverance, and the withdrawing rope device 5 can shrink drawstring 3, using lever principle, effect of the nip portion in drawstring 3
Under can around the shaft 42 rotate after cause without operating rope curtain rope control device be in disengaged position, using withdrawing rope device 5
Pulling force up pulls curtain 6, adjustment good position after, then by curtain 6 toward it is drop-down once so that without operating rope curtain rope control
Device is in clamped position, so as to fix curtain 6.The present apparatus is easy to control using simple and convenient, can be set according to different situations
Fixed different frictional force, meets the demand of different model curtain.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding can carry out various changes, modification, replacement to these embodiments without departing from the principles and spirit of the present invention
And modification, the scope of the present invention limits by appended claims and its equivalency range.
